EYE-PROTECTOR.

Application filed March 12, 1917.

To all whom it may concern v Be it known that I, GEORGE H. DAY, a citizen of the United States, residing at Southbridge, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Eye- Protectors, of which the following is a specification.

This invention relates to improvements in eye protectors and has particular reference to structures especially adapted for use in the industries.

One of the leading objects of the present invention is the provision of a simple, efficient and durable construction ofeye protector which may be readily adjusted to fit the face of the wearer. Y

Another object .of the invention is the provision of a construction in which the several parts are securely and firmly united and have sufficient rigidity to maintain their desired adjusted relation, but which are so constructed as to be capable of adjustment without the use of pliers or other tools to obtain a satisfactory fit of the protector on the face. Y

Other objects and advantages of my improved construction should be readilv apparent by reference to the following specifi'cation taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of my invention.

Figure I represents a front elevation of one form of my improved protector.

Fig. II represents a similar view illustrating an adjustment of the parts shown in Fig. I.

Fig. III represents a sectional view taken as on the line III-III of Fig. I.

Fig. IV represents a similar view of a slightly modified construction.

Fig. V represents a front view of a slightly different form of my invention,

Fig. VI represents a similar view illustrating an adjustment of this form of const-ruction.

Fig. VII represents a sectional view as on the line VII-VII of Fig. V.

Fig. VIII represents a similar sectional view of a slightly modified construction.

Fig. IX represents a view similar to Fig. VIII illustrating an adjustment of the parts.

Serial N o. 154,323.

Fig. X represents a plan view of the construction illustrated in Fig. I.

Fig. XI represents a plan view of the construction illustrated in Fig. VI.

In the drawings, in which similar characters of reference are employed to denote corresponding parts throughout the several views, the numeral 1 designates the rims for the lenses 2, which rims are preferably provided with temples or retaining devices 3 for securing the mounting in position on the face.

In the form of the invention illustrated in Figs. I to IV inclusive, I have shown the bridging or lens connecting members as formed from a single strip of material, starting as at the point 4, where one end is attached to the lenses extending across between the lens rims in the looped transversely and downwardly or diagonally extending portion 5 attached as at 6, at a diagonally opposite point from the first lens frame to the second lens frame, then being formed into the loop or spiral 7 terminating in a transverse portion 8 and suitably secured to the crest pad 9, beyond the crest pad, having a second loop l0 corresponding to the loop 7 at the other side and terminating in a second diagonally extending connecting member 11, corresponding in all essential respects to the original transverse member 5.

It will thus be noted, particularly by reference to Fig. II, that theframe just described has great possibilities for adjustment for pupillary distance, by separation of the frame through opening out of the loops 7 and 10 and through partial straightening of the looped cross members 5 and 11, while at the same time the vertical height and in and out adjustment of the crest pad 9 are readily varied as desired by opening or closing, by winding movement of the loops 7 and 10, or by desired distortion of the loops.

This adjustment may in part be readily understood by a comparison of Figs. II/I and IV, where different adjustments of the crest pad are illustrated, attention in connection with these figures, however, being invited to the fact that in Fig. III the loop is shown as extending rearwardly and downwardly to the crest pad, while in Fig. IV the loop is shown as extending forwardly and then downwardly, these two being alternative construction, either of which may be employed as desired, and both of which will present substantially the same frontal appearance and embody the same general structural features.

It will be noted that the construction just described is a one piece construction. If desired to form the bridge or lens frame connecting members in two separate parts I may if preferred make use of a construction such as for example that shown in Figs. V to IX inclusive, in which I have lshown the upper looped and adjustable bridging or connec'ting member 12, and the bridge or nose engaging member 13 having integral therewith, if desired, or separate therefrom and secured thereto, as in the preceding forms, the lateral extending vorV looped members 7 -an'd l0, which, yas in the forms just described, may extend either to the rear and then forwardly to the nose vengaging member, or forwardly and then rearwardly to the nose engaging member, alternative constructions being shown in Figs.- VII and VIII- respectively. In either event, however',- tlie bridging inember may be adjustedas desired, either byv direct upward and downward or in and out pulling movement, or preferably by a slight winding movement tending to open up or tighten the coils Iof the loops 7 'and l0 to most neatly and at the saine time satisfactorily relatively adjust the parts. The possibilities of adjustment are in part illustrated and'should be understood by a coinparison of Figs. VIII and IX, showing two Y adjustments of the same lgeneral forni of construction.

I claim:

l. An eye protector including lens frames, a connecting member formed from a single strip of material having each endV attached to the lens frames, thence` extending inwardly across between the frames, looped l transversely and downwardly and attached to the opposite lens frame, then formed into a spiral terminating ina transverse portion, and a `crest pad secured to the Itransverse portion. Y l

A'n eye protector including lens frames, a connecting member formed from a single strip of material having each end 'attached to the lens frames, thence extending inwafr'dly across between the frames, looped transversely 'and downwardly land attached to the opposite lens frames, then formed into a spiral loop, the intermediate portion of said strip terminating in 'a transverse portion and having connected thereto a central crest rest and a crest pad secured thereto for vertical in and outv and angular adjustment relative to the lens frames.

3. In an eye. protector, the combination openedVY or tightened in the plane of the loops to permit of the variance of the vertical and in and out adjustment of the nose rest.

il. In an 'eye protector, the combination with the lenses, of a round wire scroll member having one :end secured' to each of the lenses and formed in a wide scroll lying sub'- stantially in the plane of the attached ends thereof, the opposite ends of the yscroll being inwardlyV deflected andV having `connected thereto a central crest rest whereby the crest rest is supported for vertical, in and out, and angular adjustment `relative toV the flens frame, while the ldistance between the vlenses may be varied by distortion of the plane of the scroll.

5. The combination with a pair lof lens frames, vof an 'adjustablemeniber connecting the lenses and normally holding them in fixed relation one Ato the other, a nose iest, and alooped member extending from each end of the nose rest to the adjacent frame for adjustably connecting the parts.

"6. A one piece center for an eye protector or the like, comprising a pair of oppositely disposed diagonally extending looped connecting members terminating at each end in a helix or coil, of a curved central portion integral vwith and connecting the vinner ends of the helixes.

7. The combination with ja pair of lens frames, of means for rigidly holding the frames in desired adjusted position, a nose rest disposed below the lens frame, positioning means, an adjustable support for the nose rest comprising rams hor'n loops connected at one end to the nose rest and at the opposite end to the lens frame to permit of universal adjustment of the nose rest with respect to the lens frames and to accommodate desired adjustment of the lens frames with respect to veach other and thecentrally disposed nose rest. In testimonv whereof I affix my signature in the presence of "two witnesses.
